Generating a Key Pair and a Self-Signed Certificate

The genkey command of the keytool programenables you to generate a key pair.

May 20, 2016  Step 1: Generate ephemeral ECDH key pair. The first step is to generate an ephemeral elliptic curve key pair for use in the algorithm. By setting the key size to 256-bits, Java will select the NIST P-256 curve parameters (secp256r1). For other key sizes, it will choose other NIST standard curves, e.g. P-384, P-521. Java.lang.Object; java.security.KeyPair; All Implemented Interfaces: Serializable. Public final class KeyPair extends Object implements Serializable. This class is a simple holder for a key pair (a public key and a private key). It does not enforce any security, and, when initialized, should be treated like a PrivateKey. Constructs a key. The KeyPairGenerator class is used to generate pairs of public and private keys. Key pair generators are constructed using the getInstance factory methods (static methods that return instances of a given class). A Key pair generator for a particular algorithm creates a public/private key pair that can be used with this algorithm.

  1. A CSR(Certificate Signing Request) is a kind of request generated by an application and is to be sent to a Certificate Authority to create a signed certificate which can be distributed. It usually contains certificate information such as subject name, public key info and signature info. In Java, keytool can be used to generate a certificate request with option -certreq.
  2. The JOSE standard recommends a minimum RSA key size of 2048 bits. To generate a 2048-bit RSA private + public key pair for use in RSxxx and PSxxx signatures: openssl genrsa 2048 -out rsa-2048bit-key-pair.pem Elliptic Curve keys. To generate an EC key pair the curve designation must be specified.

To Generate a Key Pair and a Self-Signed Certificate

You can use the procedure below to configure the key pair and trusted client certificates to use for establishing SSL connections on the AS Java. You create a new key pair or upload an existing key pair or a trusted X.509 client certificate from the file system. The Java KeyPairGenerator class (java.security.KeyPairGenerator) is used to generate asymmetric encryption / decryption key pairs. An asymmetric key pair consists of two keys. The first key is typically used to encrypt data. The second key which is used to decrypt data encrypted with the first key. Public Key, Private Key Type Key Pairs.

  1. Navigate to the JAVA_HOME/bin directory,where JAVA_HOME is the installation directory ofthe Java SDK.

  2. Enter the following command:


  3. When prompted, enter your keystore password.

  4. When prompted, enter the Distinguished Name information.

    1. What is your first and last name?

      Caution –

      When prompted for your first and last name, make sureyou enter the machine hostname.

    2. What is the name of your organizational unit?

    3. What is the name of your organization?

    4. What is the name of your City or Locality?

    5. What is the name of your State or Province?

    6. What is the two-letter country code for this unit?

    7. Is CN=first_and_last_name, OU=organizational_unit, O=organization_name,L=city_or_locality, ST=state_or_province, C=two_letter_country_codecorrect?

  5. When prompted, enter a password for the keystore entry.If the password is same as the keystore password, press Return.

    Note –

    Ifyou want to use a keystore, it is recommended to use the sbyn.keystore file in the JavaCAPS-install-dir/repository/repository/server directory.

Java Generate Ecc Key Pair Key

To sign an assembly with a strong name, you must have a public/private key pair. This public and private cryptographic key pair is used during compilation to create a strong-named assembly. You can create a key pair using the Strong Name tool (Sn.exe). Key pair files usually have an .snk extension.

Note

In Visual Studio, the C# and Visual Basic project property pages include a Signing tab that enables you to select existing key files or to generate new key files without using Sn.exe. In Visual C++, you can specify the location of an existing key file in the Advanced property page in the Linker section of the Configuration Properties section of the Property Pages window. The use of the AssemblyKeyFileAttribute attribute to identify key file pairs was made obsolete beginning with Visual Studio 2005.

Create a key pair

To create a key pair, at a command prompt, type the following command:

Java Generate Ecc Key Pair Number

sn –k <file name>

In this command, file name is the name of the output file containing the key pair.

Generate Ecc Key Pair

The following example creates a key pair called sgKey.snk.

If you intend to delay sign an assembly and you control the whole key pair (which is unlikely outside test scenarios), you can use the following commands to generate a key pair and then extract the public key from it into a separate file. First, create the key pair: /bluesoleil-10-serial-key-generator.html.

Next, extract the public key from the key pair and copy it to a separate file:

Once you create the key pair, you must put the file where the strong name signing tools can find it.

When signing an assembly with a strong name, the Assembly Linker (Al.exe) looks for the key file relative to the current directory and to the output directory. When using command-line compilers, you can simply copy the key to the current directory containing your code modules.

If you are using an earlier version of Visual Studio that does not have a Signing tab in the project properties, the recommended key file location is the project directory with the file attribute specified as follows:
